Officially, the tech giant says that its new phone can survive up to 30 minutes at a depth of one metre.

But could it survive other, more obviously Irish challenges?

Adrian Weckler drops the iPhone 7 into a pint of stout for the test

As part of our review tests, we put the new iPhone 7 under some uniquely local pressure. We dropped it into a pint of stout. What we found was that the €800 phone can unquestionably hold its drink.

There was no bubbling, no hissing and no frozen screens. Instead, the 4.7-inch jet black iPhone 7 sat there content until, having taken a few sips ourselves, we removed it from its creamy black immersion.

When we dried it off, it was clear that the porter had not got under the iPhone's skin. The handset was utterly unfazed as we continued to click, swipe and tap our way through its various functions. (A day after conducting the test, it remains completely flawless.) Apple 1, slippery bar hands 0.

While the tech giant does not guarantee its phones from water damage (hence the word 'resistant' rather than 'proof'), Apple has a very clever way of making sure its latest gadgets remain dry.

Its updated Apple Watch - which has an elevated 'waterproof' status - expels water from its speaker grille using a system of vibrations.

While the company hasn't specified exactly what it is that is keeping water from interfering with its new iPhone 7, it may be a combination of similar technology and rubber seals around sensitive areas such as the charging port.

This isn't the only thing of note in the new iPhone 7. Apple has done away with the traditional headphone port. Even though a small adaptor to connect old headphones comes in the box, there has been some grumbling about it.

What no-one is complaining about is the new camera, which looks likely to set new standards for ordinary punters' daily photos. This is especially so on the bigger (and pricier) iPhone 7 Plus, which has a new dual camera system that lets people zoom for the first time.

The new lens also lets in more light for snapping indoor events and has better stabilisation to prevent shaky videos and blurred photos.

Already, photographers are calling it a breakthrough that will quickly raise the quality of Instagram, Snapchat and other online photos.

With more happening from its camera, the new device's battery life has had to be extended. The iPhone 7 gives between one and two extra hours per day, depending on which model you get.

Apple also launched a new wireless set of earphones called AirPods. The small gadgets, which cost €180 and come with a recharging carry case, have a microphone attached to make phone calls and last for around five hours between charges. They also allow you to use the iPhone's Siri voice command system without taking your phone out of your pocket.
